Elementary calcium reacts with water. Calcium compounds are more or less water soluble. Calcium carbonate has a solubility of 14 mg/L, which is multiplied by a factor five in presence of carbon dioxide. Calcium phosphate solubility is 20 mg/L, and that of calcium fluoride is 16 mg/L.
4/ All sulfates, except barium, strontium, calcium, silver and lead(II), are soluble or slightly soluble. 5/ All carbonates, except the group 1 and ammonium carbonates, are insoluble. 6/ All hydroxides, except the group 1 and ammonium, barium, strontium and calcium hydroxides, are insoluble.NaCl-is a group 1 salt, so is soluble. PbSO4 - is an insoluble sulfate. Zn(NO3)2 - all nitrates are soluble./ All hydroxides, except the group 1 and ammonium, barium, strontium and calcium hydroxides, are insoluble.
